SLOT-IRON FOR CABLE RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 333,205, dated December29, 1885.

Application tiled September 11, 1885. Serial No. 176,826.

To all whom it may concern:

Be it known that I, EDWARD D. DOUGH- ERTY, of Philadelphia, in thecounty of Philadelphia and State of Pennsylvania, have invented certainnew and useful Improvements in Slot-Irons for Cable Railroads; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to an improvement in slot-irons for cablerailroads, the object of the same being to provide a strong and durableslot-iron that can be easily and quickly adjusted to increase ordecrease the size of the slot through which the grip passes.

A further object is to provide the adjustable slot-iron with a removablewearing-face, whereby the parts exposed to wear can be renewed in ashort space of time without the necessity of tearing up the road-bed orstopping travel; and with these ends in view my invention consists inthe parts and combinations of parts, as will be more fully described,and pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of aslot-iron embodying my invention, and Fig. 2 is a view in transversesection showing the iron applied to one form of supporting-bracket.

A represents a bracket of any approved design, having a slot, a, for thepassage of the grip to the cable, located within the tube Band seats bfor the rails. The slot-irons C are seated on the bracket on'oppositesides of the slot, and each consists of a broad base, c, a web, c',extending upwardly from the central portion of the base and inclinedinwardly, and an inwardly-projecting flange, c2, constructed integralwith the web c and forming a seat for the plates D. The base of eachslot-iron is provided at suitable intervals apart on opposite sides ofthe web c with the transverse elongated openings d, through which thebolts E, which secure the slot-irons to the bracket, pass. The base ofthe slot-iron 'may also have recesses therein communicating with theboltopenings d for the heads of the bolts; but the device is just asefficient if the heads of the (No model.)

bolts rest on the upper surface of the base. The openings d are of alength suflicient to permit the slot-irons to be moved inwardly to takeup the wear, and as this inward movenient is comparatively small, thebolt-heads can be made large enough to cover the openings and preventdirt from entering therein. Instead ofthe above, the bolts can beprovided with sheet-metal washers below the heads and answer the samepurpose. The bolts E pass through the base and brackets and are securedinto screw-threaded openings in the brackets, or they can project belowthe bracket and be secured by nuts, as shown in the drawings. The upperface of the flange c2 is flat, and forms a seat or rest for thewearing-plates D, which, in the present instance,

are provided with corrugated upper surfaces,

for the purpose of preventing horses from slipping thereon. Thesewearing-plates are yremovably secured in position by bolts or otherwise,and each is provided with an inwardlyprojecting lip, which latteroverhangs the inner edges of the flanges of the slot-irons and takes allthe wear occasioned by contact with the grip. The upper surface of thisinwardlyprojecting lip is concaved to prevent horseshoe-calks frombecoming wedged or sticking.

By means of the above improvement I am enabled to adj ust the slot-ironsto take up any wear, and am also enabled to remove the portion subjectedto the wear and replace it at a small cost in a few moments withoutstopping trafc.

It is evident that numerous slight changes in manner of securing theslot-irons to the brackets might be resorted to hence I would have itunderstood that I do not confine myself to the exact construction shownand described, but consider myself at liberty to make such changes asfairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with an adjustable slotiron, of a corrugatedwearing-plate removably secured to said adjustable slot-iron,substantially as set forth.

2. The combination, with a laterally-adjust mately from the center ofthe base,theinward able slot-iron, of wearingplates removably sely-projeoting flange, and a 4removable weareured to said slot-irons.ing-plate, substantially as set forth.
